What is net force?

• The force exerted by an object on itself

• The force required to move an object

• The force exerted by an object on another object

• The overall force acting on an object, taking into account the magnitude and direction of all individual forces.

When the net force on an object is zero, it means the forces are:

• equal

• opposite

• balanced

• unbalanced

What is the formula to calculate net force?

• The average of all the forces acting on an object.

• The sum of all the forces acting on an object.

• The product of all the forces acting on an object.

• The difference between all the forces acting on an object.

If two forces are acting in the same direction, what happens to the net force?

• The net force decreases.

• The net force remains the same.

• The net force increases.

• The net force becomes zero.

If two forces are acting in opposite directions, what happens to the net force?

• The net force is the difference between the two forces.

• The net force is zero.

• The net force is equal to one of the two forces.

• The net force is the sum of the two forces.

What is an example of balanced forces?

• A person pushing a box with the same amount of force as another person pulling the box in the opposite direction.

• A person pushing a box with the same amount of force as another person pushing the box in the same direction.

• A person pushing a box with less force than another person pulling the box in the opposite direction.

• A person pushing a box with more force than another person pulling the box in the opposite direction.

What is an example of unbalanced forces?

• Pushing a car with more force on one side than the other

• Pushing a car with equal force on both sides

• Pushing a car with more force on the back than the front

• Pushing a car with more force on the front than the back

If the net force on an object is 0 N, what can you say about its motion?

• The object is accelerating.

• The object is moving in a circular path.

• The object is either at rest or moving with a constant velocity.

• The object is moving with a variable velocity.

If the net force on an object is greater than 0 N, what can you say about its motion?

• The object will be moving at a constant speed.

• The object will be decelerating.

• The object will be accelerating.

• The object will be at rest.

If the net force on an object is less than 0 N, what can you say about its motion?

• The object is likely to be accelerating in the opposite direction.

• The object is likely to be slowing down or moving in the opposite direction.

• The object is likely to be at rest.

• The object is likely to be speeding up or moving in the same direction.
